FURNACE WALL.

Application filed March 26, 1924. Scria1 No. 701,943.

To all whom it may cance /'11,:

Be it known that I, ARTHUR L. SCHEY- ING, a citizen of the United States, residing at Chicago, in the county of (look and State of Illinois, have invented certain'new and useful Improvements in Furnace Walls, of which the following is a specification.

This invention relates to walls for furnaces, and, particularly walls which are exposed to high temperatures, such as walls of boilers, metallurgical and steel furnaces, and the like. One of the objects of the invention is to provide a wall arranged so that injuries thereto may be conveniently and quickly repaired, particularly without disturbing or injuring such portions of the wall as are not in need of repairs. Another object of the invention is to provide a wall which can be quickly and conveniently assembled and which is inexpensive and dependable.

This invention is a modification of the invention disclosed by my patent application Serial No. 613,110, filed January 17, 1923, and for details of the invention which are not material to this application reference may be had to the said former application.

Of the drawings of the application Fig. 1 is an elevation of a portion of the outer wall; Fig. 2 is a sectional view along the line 2-2 of Fig. 1; Fig. 3 is an elevation of a portion of the inner wall; Fig. 4 is a detail view of a portion of Fig. 2; and Fig. 5 is an elevation of a portion of the edge of the double wall; all of which embody features of my invention.

In general, the wall which I disclose is a combination of'two wallscomprising aninner wall and an outer wall 11, having an air space 12 between the two walls. The walls are substantially air tight and the spaces between the walls are sealed in any suitable manner. A frame is provided for supporting the walls. While any suitable frame may be used, I prefer for the purpose uprights composed of a pair of L-beams 13,

which are riveted together with a plate 14: between. The plate extends inwardly and outwardly each side of the outer wall 11. The outer edge of the plate has slots 26 through;which, pass straps 27, and in these straps are screws 28 by means of which the sections of the wall 11 are pressed firmly against the flanges 29 of the beams 13- In this manner the sections of the wall 11 may be very conveniently removed or installed. To remove a section of the walls it is necessary only to remove the straps 27.

The plates 14: are connected together by means of pipes 16 through which pass bolts 17. The bolts also pass through the plates and the plates are thus bolted firmly to the ends of the pipes by means of the nuts 18. In this manner a frame is formed which supports the outer wall and forms a support for preventing any horizontal movement of the inner wall, and by removing the bolts 17, the outer Wall which is formed in sections or portions thereof, may be conveniently removed, so as to have free access to the outer side of the inner wall.

The inner wall is'preferably composed of suitable fire bricks 20 cemented together work of the walls so as to hold them firmly in place and to prevent displacement thereof by air pressure or other warping tendencies, or during any repairs of the wall.

The means which I prefer for holding the bonding blocks in place comprises clips 23 which are formed in two complementary pieces and are adapted to be bolted together by means of bolts 24 so that the outer ends 25 of the clips extend around and clamp loosely the tube 16, while the inner ends clamp the projections 22. In this manner the bnding blocks are held from displacement with reference to the frame but slight movement thereof is allowed, such as would result from longitudinal or rotary movement of the clips 23 on the tubes 16. The bonding blocks, however, are held firmly against horizontal movement with reference to the wall, and any bowing or bending of the wall is thus prevented.

If, however, the bricks of the inner wall are injured by the intense heat of the fire so that it is necessary to repair the wall, the outer sections 11 of the wall opposite the injured place may be removed, if desired, and the particular bricks which are injured can be readily driven out\ from the wall or removed in any suitable manner without disturbing the remainder of the wall; and any bonding blocks that need to be replaced may be quickly removed, and bricks and blocks may then be substituted without in any way injplring or disturbing the remainder of the wa I claim as my invention:

1. A vertical furnace wall comprising a plurality of fire-blocks incombination with a plurality of bonding blocks interspersed among said fire blocks and forming a vertical wall, and means for holding said bonding blocks in place, said means comprising a frame work, a' bar fixed to said frame work, and clips arranged to detachably clasp said bar and the ends of said bonding blocks.
